Don't know about those modern drives, but I used to use years ago smallish hd, which had some bad blocks. I used ABTools to mark them out of use. In fact ABTools makes one file visible on filesystem, which lays over bad blocks. So the drive works if you don't remove that file or reorg or something. Downside is that ABTools works only with original FFS.. that means that there's that usual 2/4G limit in partition/hd size. With one bigger drive I just didn't use the area where I found the bad blocks to be. Just left it without any partitions.
